68 JOURNAL OF CONCHOLOGY, VOL. II, NO. 3, JULY, I904. 



H. virgata (or H. variabilis to adopt the more sensible name of 

 continental conchologists). — Whereas in England we are accustomed 

 to find the type and the yellowish and the whitish (albida not alba) 

 forms associated, and in about equal proportions, the type here 

 seemed not so common, and var. albida hardly found. The well 

 marked var. radiata I found both inland and by the sea. The com- 

 monest form was a greyish yellow with one or more brown zones or 

 markings above the periphery. No forms were large and it seemed 

 to be here of a decadent race. 



H. caperata. — Two specimens seem to Mr. Edgar Smith to be 

 H. caperata^ but it is difficult to distinguish between this and H. 

 boissyi, and Dr. Hidalgo is doubtful of its having been found in 

 Majorca. 



H. conoidea. — The same, I think, as Dr. Hidalgo's H. trochoides, 

 is local. I first found it on the sea shore shrubs near Lagos de St°- 

 Ponsa, but afterwards, finer and much more well marked and varying, 

 at Belver. They are beautifully marked little shells and vary very 

 much. There is one curious variety in which all the shell except the 

 white apical whorl becomes chocolate. It seems to bear somewhat 

 the same relation to H. acuta, as regards marking, habits, etc., as 

 Vertigo does to Pupa. The slightest touch makes them drop from 

 twig or blade, so that I found it best to hold a glass tube under them 

 into which they dropped on their support being touched. They 

 much resemble the seed vessel of a plant on which they are often 

 found. They were in copula on December 8th. 



H. (Turricola) terrestris was plentiful, and finer inland than 

 by the sea. Moquin-Tandon, I believe, makes the fasciated variety 

 the type, and the uniformly grey shells var. grisea. Here, however, 

 var. grisea prevailed, and any with dark bands were rare. I found one 

 curious scalariform specimen. 



H. pyramidata I found about Cas Catala. It looks like a 

 pyramidal variety of H. virgata until the flat base and the absence of 

 umbiUcus is noted. I found it almost exclusively on young fir trees. 

 It has its beautiful var. radiata like H. virgata. 



H. lenticula was common under stones in comparatively damp 

 places, i.e., not much on the hills. It resembles our Patula 

 rotundata but has not its markings. 



H. prietoi is more easily distinguished by being strongly ribbed, 

 especially on the lower side, and having a cristate keel. 



H. ponsi I found sparsely under stones. It somewhat resembles 

 H. caperata, but has a strongly marked keel. 



H. boissyi is another of this group much resembling its congeners. 



H. apicina was common on sandy places with low vegetation. I
